How much does a garden office cost?

16th July 2025

The Garden Office Cost Breakdown

Whether you’re dreaming of a compact office pod to work from home or a fully kitted-out workspace with all the extras, this guide breaks down everything you need to know. From self-build kits to professionally installed solutions, we’ll explore what’s included, what affects the price, and how to find the right option for your space and budget.

How much does a garden office cost?

The cost of a garden room will depend on several factors, including height, depth, width, placement, and upgrades. So there are plenty of options to suit your budget when shopping around for a garden office.

If you’re working on a tighter budget, you can opt for a self-build garden room starting from as little as £9,995. This entry-level price is ideal as a compact garden office pod for one person to work comfortably.

From there, the price increases depending on the size of the building and any optional upgrades you choose, such as cladding finishes, bifold doors, or air conditioning.

If you have more flexibility within your budget, but are limited on size, the smallest garden offices start from £12,485 for a 2.5m x 2.5m building.

After something bigger? Our largest garden offices cost £43,450 for a 30 square metre internal measurement building.

Between the smallest and largest sizes, we offer over 70 different size configurations to choose from. Our measurements increase in modular half metre increments so that you can find a size to fit your space and needs perfectly.

So, you know how much a garden office costs; now here’s what’s included!

Unlike many other garden room companies, what you see is what you get with Green Retreats. Our garden offices come with everything you need to get started, with no hidden extras!

Here’s what’s included in the price of your garden office:

 

Built to Last

Every garden office we build comes with durable, maintenance-free redwood cladding and a robust steel and PVC-coated roof. Designed for longevity, our materials require minimal upkeep, so your space stays looking great for years to come.

 

Comfortable in Every Season

Each building features premium-grade insulation in the walls, floor, and roof to ensure year round usability. We also use Pilkington K Optiwhite double glazing, helping to keep your office warm in winter and cool in summer. Heating is included as standard, so you can work comfortably.

 

Bright, Secure Spaces

Enjoy natural light through your choice of wide 2.3m French doors or sliding doors, paired with a full-height window and a signature lozenge window opening. All our glazing features insurance-rated locks, offering added peace of mind for your workspace.

 

Modern Interiors, Ready for Work

Inside, you’ll find soft-sheen melamine walls, oak-effect laminate flooring, and sleek graphite and black flashing surrounds. The clean, modern finish creates a professional space that’s easy to personalise.

 

Power Where You Need It

Your garden office comes ready with everything you need to plug in and get started. We include internal and external lighting, a consumer unit, and three double plug sockets. All wiring is completed and ready for final connection by your electrician.

Make It Yours with a Choice of Upgrades

While every garden office includes a generous range of standard features, you can also customise your space with a wide selection of optional upgrades.

Add the finishing touches that matter to you, like bi-fold doors, air-conditioning, underfloor heating, plastering, painting, and so much more.

…or retrofit after we’re done!

Your garden office is a blank canvas, ready to become whatever you need it to be. The best part? Moving in and making it your own.

Over the years, we’ve seen customers transform their spaces into stunning interior-designed rooms, fully kitted-out garden bars, or even add bathrooms and kitchenettes after installation.

The space is bright, with natural light streaming in through the sliding glass doors, which open to a lush garden outside. A folding chair with stickers is positioned near the door, and a white armchair can be seen in the corner, adding to the room’s relaxed atmosphere.

Other Costs to Consider with Your Garden Office 💡

Even once you know the base price, here are a few extras to keep in mind:

  • Delivery
    Included within 100 miles of our Buckinghamshire factory (HP18 0XB). Beyond that? We’ll calculate a fair quote during your consultation.
  • Levelling
    We install concrete mini-pile foundations, but your plot needs to be level within 200 mm. If it’s not, grab a few landscaping quotes; no need to prep the ground before your site survey.
  • Planning Permission (if required)
    Most garden offices don’t need this. If yours does, based on size or placement, we’ll handle the entire application process for you.
